Cost estimation in software engineering

Methods

Methods for estimation in software engineering include this principles:

• COCOMO, the first version known as COCOMO 81 and the second as COCOMO™ II
• COSYSMO
• Evidence-based Scheduling Refinement of typical agile estimating techniques using minimal measurement and total time accounting.
• Function Point Analysis
• Parametric Estimating
• The Planning Game (from Extreme Programming)
• ITK method, also known as Method CETIN
• Proxy-based estimating (PROBE) (from the Personal Software Process)
• Program Evaluation and Review Technique (PERT)
• Putnam_model, also known as SLIM
• PRICE Systems Founders of Commercial Parametric models that estimates the scope, cost, effort and schedule for software projects.
• SEER-SEM Parametric Estimation of Effort, Schedule, Cost, Risk. Minimum time and staffing concepts based on Brooks's law
• The Use Case Points method (UCP)
• Weighted Micro Function Points (WMFP)
• Wideband Delphi
